LOGKSMITHS VISE.

Application filed April 6, 1922. Serial No. 550,120.

To all whom it may concern:

Be it known that I, THOMAS EDWARD ELZY, a citizen of the United States, residing at St. Louis, in the county of St. Louis City and State of Missouri, have invented new and useful Improvements in Locksmiths Vises, of which the following is a specification.

This invention relates to tools, particularly to vises, and has for its object the provision for a vise designed for use by lockismiths for holding a lock cylinder core while the pins are being filed, the construction of the device being such that the operator has both hands free to operate and control the movement of the file when working upon the pins. An important object is the provision of a device of this character which is designed for use in association with and to be mounted upon a suitable bracket which may be mounted upon a work-bench of any character whereby the various parts may be held rigid so as to prevent any possibility of slipping of the lock cylinder core within the jaws of the vise.

An additional object is the provision of a device of this character which will be very simple and inexpensive in manufacture, highly efficient in use, positive in action, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed andillustrated in the accompanying drawings in which- Figure 1 is a side elevation of my vise associated with a bracket which may be mounted upon a work-bench.

Figure 2 is a longitudinal sectional view through the vise alone.

Figure 3 is a vertical cross section.

Referring more particularly to the drawings, the letter A designates a portion of a suitable work-bench, table or other'support. In carrying out my invention I provide an elongated bracket 10 preferably of the shape shown which is suitably secured upon the support by means .of bolts, screws, or the like, and this bracket has its free end terminating in an upwardly extending por tion 11 which carries a plate-like support 12 which is preferably horizontally disposed.

The vise ro er consists of a substantiallv rectangular body 13 which may be formed a single casting or which might be formed in any desired manner if preferred, and this body is held upon a plate 12 by means of screws 14 or the like. This body is bifur cated so as to be of U-shape and the bifurcation 15 leads intoa pair of oppositely disposed substantially semi-cylindrical recesses 16. This entire body might be formed of hard steel, tempered or case hardened as pre ferred, or may be formed of brass, bronze, or other comparatively soft material, in which latter event the upper end thereof would be provided with hardened steel Ta,

plates 17. The ubstantially semi-cylindrical recesses 16 are of a mating nature and are therefore adapted to receive a lock cylinder core indicated at B, which is provided with a slot 0 and with which is associated a key D in association with which are disposed the tumbler pins E to be filed. As is well known, such pins, when placed in position, will project above the surface of the vise at varying heights.

Slidable within the bifurcation of the body is a lock block 18 which has a curved upper face 19, which forms an arc of the same circle defined by the mating recesses atthe opposite sides of the bifurcation in the body. Threaded through the lower portion of the body are screws 20 which engage against the underside of the block 18 and which are for the purpose of wedging the block upwardly into clamping engagement with the cylinder core B.

In the operation of the device it will be seen that the core B is slid into the substantially semi cylindrical recess defined by the mating recesses 16 and the curved upper end of the block 18. The key is inserted in place and the various pins to be filed are also placed in association with the key and the cylinder. The screws 20 are then tightened and the consequent upward forcing of the block 18 will result in firm clamping engagement of the cylinder core in the vise so that the pins and in fact all the parts will be firmly held so that the operator will have both hands free for filing of the upper ends of the pins flush with the top of the body.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very simply constructed device for the purpose described which will very efiiciently operate to hold securely a lock cylinder core, key and pins in absolutely rigid position and in the proper relative positions with respect to one another so that filing off of the pins may be accomplished in a remarkably short time and with the utmost case.

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

hat is claimed is l. A device of the character described comprising a supporting arm carrying a head, said head being formed with a bifurcation communicating with a partially cylindrical recess which merges into one end of the head, a block slidably mounted Within the bifurcation toward and from the longitudinal axis of the cylindrical recess, a guide rod carried by the block and slidable through the closed side of the head, a spring on said rod normally urging the block away from the recess, and a pair of screws threaded through the closed end of the head and bearing against said block whereby to move the same into clamping engagement with an object within the recess.

2. A device of the character described comprising a supporting arm carrying a head, said head being formed with a bifurcation communicating with a partially cylindrical recess which merges into one end of the head, a block slidably mounted within the bifurcation toward and from the longitudinal axis of the cylindrical recess, a guide rod carried by the block and slidable through the closed side of the head, a spring on said rod normally urging the block away from the recess, and a pair of screws thread ed through the closed end of the head and bearing against said block whereby to move the same into clamp lng engagement with an object within the recess, said screws being parallel with said guide rod and all being arranged at right angles to the longitudinal to axis of the recess.

In testimony whereof I affix my slgnature.

THOMAS EDWVARD ELZY.
